The popup message is still there, and moreover it added a new one 

Windows 3DCoat 2026.16 HOTFIX Portable 3DCoat, 3DCoat Textura, 3DCoat Print - Fixed an issue with installing Python modules when folder names contain spaces. - Pre-installed AV library in Python

I'll look into why this message is appearing.

I'll look out for this file, because I've made couple more since then, so don't remember which one has that error.  One thing though, I think I've done it in 2025.17, so maybe 2026.12 is better with handling retopo mesh.

I have the same popup warning each time opening the program after updating to 2026.15 hotfix 

Layers ungrouped Same Layers grouped, note the gloss difference on the bottom blue strokes  

A popup warning appears when I was moving layers to group on 3DCText

I wouldn't call this solved.  I've done multiple clean installs and my top menu is still missing, I've tried all the solutions I could find connected to this thread and nothing worked. I've had to go back to 2025.17 to get it working again.

Hi! 3DCoatTextura 2026 exports Color/Albedo maps with a white background instead of transparency/padding how it was in 2025 version. I'll attach the screenshots of how it used to be and how this looks now. I tried all formats like png, jpg, but it has the same white color. The psd version is better, but it breaks the clipping mask (with which I also had problems and have written already about). Just in case, the padding in Preferences is enabled, but it has no effect on the exported texture. Could you help me please?

Make clipping mask (filled w/ Smaterial or w/Smaterial attached) - This option it is not working - Neither this - Result  

This bug was solved on the new release. thanks for point it up

I would like to report a bug potentially relate to this patch note from 2025.12 patch: - New plane pick mechanics: if you click quickly, the RMB menu appears. Click longer to select a point and a plane. [that was before] Changed: Hold RMB to move the plane's central point over the surface, but keep it normal. Press CTRL to move the plane along the normal. I have attached a video here to detail the bug. I would really appreciate if the developer can look into this. Thanks! 3Dcoat_bug_072726.mp4
